This is a 5-problem quiz/practice to help students better understand how to sum forces to find the net force on a particle.

Through interactive examples and practice problems, this tutorial helps students understand net force-acceleration problems in which an applied force is directed at an angle to the horizontal.

[Free Registration/Login Required] Shown are three different systems with two forces acting upon it and a red vector showing the net force acting upon the system. Move the red dots to accurately reflect the net force experienced by each...

Students combine their understanding of acceleration and the fact that a net force causes an acceleration to determine whether or not a net force exists in several practice situations. After each problem, they are able to check their...

This game is intended to help students master the idea of net force for non-parallel forces. Students will have three minutes to figure out as many net forces as possible.

Explains three forces of nature and how they impact the weather. These include infrared rays from the sun, differences in air pressure, and wind flow when hot and cold air masses meet. Supported by lots of visuals.

In the following interactive students will begin to define net force, external force, and system and understand Newton's second law of motion. They will also apply Newton's second law to determine the weight of an object.

Through examples and practice problems, this interactive tutorial helps students understand forces that are in a state of equilibrium with a net force of zero.
